maggport

A mongodb aggregate export CLI tool

Overview

maggport is a python CLI tool designed to bridge the gap of exporting aggregate pipeline(s) in mongodb. What used to be feat accomplished by writing your own shell script or exporting a custom mongodb collection to csv or JSON, generated by running an aggregate pipeline, can now be achieved by this tool.

Installation

pip install maggport

Example 1

Passing pipeline as a parameter and output results in terminal.

maggport --host sample_host --port 8080 --db food --collection fruits --pipeline '[{"$group": {"_id": "$name", "count": {"$sum": 1}}}, {"$match": {"count": {"$gt": 1}}}]'

Output:

[
    {
        "_id":"apple",
        "count": 3
    }
]

Example 2

Passing pipeline as a file and output results in terminal.

pipeline.txt

[
    {"$group": {"_id": "$name", "count": {"$sum": 1}}},
    {"$match": {"count": {"$gt": 1}}}
]

maggport --host sample_host --port 8080 --db food --collection fruits --pipeline-path pipeline.txt

Output:

[
    {
        "_id":"apple",
        "count": 3
    }
]

Example 3

Export results as csv file.

pipeline.txt

[
    {"$group": {"_id": "$name", "count": {"$sum": 1}}},
    {"$match": {"count": {"$gt": 1}}}
]

maggport --host sample_host --port 8080 --db food --collection fruits --pipeline-path pipeline.txt --out test_results.csv

Output:

test_results.csv
